That is some good news to hear. I appreciate that you're getting it looked into and as I'm sure with all good feedback it'll only make the game even better. Did not know this issue could be tied to FPS... it would explain why I had such difficulty. Hopefully going forward it'll just be locked to 30 or less that way it's less hard on the hardware. I noticed it really ate up a lot of frames. Best of luck to getting it resolved.
I didn't have time to include a Controls section in the menus for this hotfix, but my friend confirmed me that the pressing a Monster bug that was happening to him (very, very similar to yours), is fixed now. If you try the new version one of these days, I hope it's fixed now and it's not unpleasant to play! Apparently for this particular fix, it was indeed related to high Hz monitors (so the game goes at higher FPS -> less time to click correctly. Eventually I'll also include a way to cap FPS, so monitors with a high Hz don't try to perform the game with the highest possible FPS, causing unnecessary overwork.
